Patented July 26, 1932 PATENT OFFICE LAJ OS SOLII, OF PECS, HUNGARY LOCKING DEVICE Application filed April 26, 1930, Serial No. 447,628, and in Hungary September 20, 1929.

Looking devices are known which consist of a fixed empty lock casing and of an exchangeable lock fitting into this look casing, elastic hooks engaging from outside through suitable openings of the casing with slots cut into the lock or with stops on the lock being provided on one narrow side or both narrow sides of the lock casing, by which elastic hooks the lock is fixed in the lock casing and which may be disengaged by hand when taking out the lock from the lock casing.

Now, applicant has found that in looking devices of this kind it is a'drawback of the method described above of fixing the lock in the lock casing, particularly in the case of mortise looks, that owing to the fact of the elastic hooks being arranged outside the lock casing a larger recess must be cut out by mortising than would be required for the lock itself. j

In the present invention this drawback has been avoided. The locking device according to the invention therefore presents, in addition to the well-known advantages of locking devices consisting of an empty lock casing and of a lock body arranged inside such casing, the further advantage of the lock casing consisting of a simple box on which there are no projecting outside parts, for

39 which reason it can be manufactured in a more simple manner and at less cost, and can be mounted in any place very easily.

According to the invention, a spring M pressed gib is provided in the lock itself P" which projects from one of the narrow sides of the lock through a corresponding opening of the lock casing. If the lock is being opened i. e., if the bolt of the lock is in the closed position, this elastic gib will abut against the bolt, and can therefore not be pressed down, and the gib accordingly fixes the lock in the lock casing, while if the bolt is driven outwards by means of the key, the elastic gib can be pressed into the lock, which being done, it becomes possible to lift out the lock, holding it by its bolt, from the lock casing.

The accompanying drawingexemplifies an embodiment of the invention.

Figure 1 is a front view of the lock casing with the lock inside it.

Figure 2 is a side view of the same.

Figure 3 is a plan view of the same.

Figure 4 is a front view of the lock drawn 5. out from the casing, with the cover plate of the lock removed and with the bolt in closed position.

Figure 5 is the same, but with the bolt in the opened position.

The lock or lock body a is slid into the lock frame or lock casing c, on one narrow side of which a slot 1) is provided, and which look frame or look casing is to be fixed on. the object as drawer, chest, or the like, to be locked Figures 1 to 3. The lock is fixed in the lock casing by means of the spring pressed gib projecting through the slot 5 of lock casing 0 from one of the narrow sides of lock a. A. spring a is, besides, arranged at the end of the lock casing, which spring tends to drive the lock out fromthe lock casing, and therefore presses the gib d of the lock to the wall of slot 6.

This gib cl is pivot-ed on pivot e of the lock body a, and carries a peg f against which the spring h of the usual tumblers 9 rest, Figures 4 and 5. The gib d possesses, besides, an extension piece 2' extending from the gib downwards which extension piece in case of the lock being open i. e. in case of the closed position of the bolt, Figure 4, abuts against the bolt 7', that is to say against the extension plece j of the bolt. It is therefore impossible when the lock is open to press the gib d into the lock body.

If it is desired to lift the lock body at out from the lock casing 0 the bolt 7' is driven out from the look by means of a key, Figure 5, and the gib d is pressed into the lock by means of the operators finger or. by means of a peg Z inserted through the hole is provided on the locking face of the lock, Figure 2, which peg presses the surfacem of the gib (5 down. Gib cl now occupies the position 95 shown on Figure 5 and thus the look a can be pulled out from the casing 0 holding the look by the latch 7'. The spring n arranged at the end of casing 0 drives the lock out from the lock casing when the gib d is pressed down. The disengagement of the spring pressed gib (Z can also be effected by other suitable means.

WVhen replacing the lock, the lock which is in the opened position Figure 5 is simply slid into the lock casing until the elastic gib (Z snaps into the opening Z) whereby the lock becomes fixed in the lock casing.

What I claim is 1. A locking device including in combination a fixed lock casing have one end open and having an aperture in the top wall near the open end, a lock insertable in the lock casing and including a lock body, a sliding latching bolt on the body, a tumbler plate associated with the latching bolt, a gib pivotally mounted on the lock body and adapted to project through the aperture in the top of the casing when the body is arranged in the casing, a spring connected to the tumbler plate and acting on the gib to hold it in an extended position, coacting extension pieces on the gib and on the latching bolt which in the retracted position of the bolt prevent depression of the gib so as to fix the lock body in the lock casing whilst in an extended but unlocking position of the latching bolt the gib can be depressed on the lock body whereupon the lock body can be drawn out by its latching bolt from the lock casing.

2. A locking device including in combination, a lock casing, a. lock insertable in the casing and including a lock body, a sliding latching bolt thereon and a tumbler plate associated with the bolt, a spring pressed gib mounted on the lock body projecting through the top wall of the casing and in the retracted position of the latching bolt resting against the latching bolt so as to fix the lock body in the lock casing while in the extended position of the latching bolt it is adapted to be depressed on the lock body so that the lock body can be drawn out by its latching bolt from the lock casing, a peg mounted on the gib, and a spring mounted on the tumbler plate and bearing against the peg so as to control the action of both the tumbler plate and the gib.

3. A locking device including in combination, a lock casing, a lock insertable in the casing and including a lock body, a sliding latching bolt thereon and a tumbler plate associated with the bolt, a spring pressed gib mounted on the lock body projecting through the top wall of the casing and in the retracted position of the latching bolt resting against the latching bolt so as to fix the lock body in the lock casing while in the extended position of the latching bolt it is adapted to be depressed on the lock body so that the lock body can be drawn out by its latching bolt from the lock casing, and the gib being provided with a downwardly sloping front face adapted to be engaged and pressed down- Wardly by an insertable peg when the latch ing bolt is in an extended but unlocking position.

In testimony whereof I affix my signature.
